But it's also a recognition of an honorable practice that not everyone follows. Outlets that mark their corrected articles clearly or collect them in one easily searchable section (for example, The Guardian) may be over-represented in this list, but they should be commended.

A note on selection: This is a list of media corrections, not media errors. Barring two errors that were retracted without acknowledgment (boo!), we did not include slip-ups that went uncorrected.

Pre-writing obituaries of ailing global figures is a logical strategy for newsrooms. However, canned obituaries require close editing, which CNN's note on how many U.S. presidents Castro outlived did not receive.

EDITOR'S NOTE: Comments attributed to a Trump campaign spokeswoman were removed from an earlier version of this story at her request after she learned she would be identified by name.

Several Italian newspapers used a photo of an impersonator to accompany news of Bob Dylan's Nobel prize. To this author's knowledge, none has published a correction. (This is not infrequent, unfortunately, but usually it is breaking news stories on terrorist attacks that get wrong photos associated to them).

When dedicating an article to a presidential candidate's foreign policy inexperience, it is helpful to have a good grip on the main cities in the region involved. Otherwise, you may end up having to correct yourself. Twice.

The Express in the United Kingdom ran a error-infested gallery titled "Amazing things we get back if we leave EU." Here's their rendition of the error, our emphasis added:

The gallery was formed of 11 images. Each image carried a caption. The captions for images 3 (eggs), 5 (jam), 6 (water) & 9 (swedes) were inaccurate. In the case of caption 3 (eggs), the caption claimed that "A dozen eggs: In 2010 the EU said that food could not be sold by number but by weight". In 2010 the European Union was considering legislation governing food labelling. In June 2010 Renata Sommer the MEP responsible for steering the legislation confirmed 'There will be no changes to selling food by numbers". In fact a consumer who purchased eggs in the UK would be able to do so by number. Caption 3 (eggs) was therefore incorrect. Given that 4 of the 11 captions were incorrect this gallery has been deleted.
